Entomology

Key to the Melanoplus Species

Previous Step (E)

F General color above green to brown with a yellow-buff stripe on each side extending from behind the eye, along margins of pronotum and converging on tegmina; hind femora with longitudinal stripe on outer surface; hind tibiae variable; widely distributed; our common large grasshopper and a serious urban and agricultural pest.
 

Hind femur Cercus
Melanoplus bivittatus (Say)


F' General color as viewed from above uniform olive to brown, occasionally yellow or black.

Go to G


<G Black bands form herringbone pattern along entire length of hind femora; hind tibiae yellow; a black morph and a yellow morph occur as a small percentage of the population; widespread and common in agricultural and urban environments.

 
Hind femur Cercus
Melanoplus differentialis (Thomas)

Hind femur of black morph of M. differentialis
[The black morph of M. differentialis may lack the banding pattern along the entire length of the hind femur, resembling M. ponderosus; the distinct black color, however, clearly indicates M. differentialis.]


G' Black on outside face of hind femora forming two or three diffuse bands; hind tibiae orange to red; uncommon.

 
Hind femur Cercus
Melanoplus ponderosus (Scudder)
